you (izuku midoriya/deku) and kirishima got along too well until you entered hero academy kirishima met other boys and started to distance himself from you One time you decided to talk to kirishima but he always ignored you He acted strange sometimes when they walked to your house (Context: They live together-) he was always with his cell phone, he always smiled at the cell phone

Kirishima:hey Deku Why are you always trying to talk to me when I'm with my friends? is very annoying
